  1. indeed, it is B. hehe! awww... how come no one laughed at my joke... nah! it was not even a joke. 'twas just a stupid post..
  2. wahehe!! i like your signature. hehe!! so who's lying among the three (A, B, C)? hehe!! i bet its D!
  3. hmm.. since were already on the topic of ionosphere, tesla etc. is it possible to transmit electric charges directly to the ionosphere? lightning strikes downward right? can we reverse this?
  4. yes, i guess its more on the heat removal rather than drowning it with CO2. your breath is at a lower temperature than the flame. your breath gets some of the heat from the flame. and this action makes the fire triangle or fire tetrahedron crumble.
  5. does anyone of you know any online calculus exams? please, if you do know one, put the website or URL. its summer here and i can't go inside our school library cause i'm not yet a "registered" student. and i can't go to our public library since i still have a standing balance there. heehhe!! please help. i tried google and i did not find what i was looking for.
  6. yeah.. that's how to get the answer.. I guess.. y = x + sin(xy) dy/dy = 1 + cos(xy) * (y + x dy/dx) (Use of Chain Rule) dy/dx = 1 + y cos(xy) + x dy/dx cos(xy) [dy/dx-(x dy/dx cos(xy))] = 1 + y cos(xy) dy/dx [1 - x cos(xy)] = 1 + y cos(xy) (simplifying the equation we arrive to..) dy/dx = [1 + y cos(xy)]/[1 - x cos(xy)] ---> my answer... hope its correct.. hek hek hek!! xiao!
  7. your function is quite hard to answer since it will go on a circle. if we try to substitute y in x + sin(xy) we still have y. it is also quite hard since we have two variables. though i haven't answered it yet, these are some of my points regarding your question. i'll try to solve this later. hope i can answer it. till next time!
  8. hey, are you trying to synthesize the molecules in the ozone layer? that's great.. i was planning a project like this for a science fair. but unfortunately it was kind a hard for me so i switch to biodiesel instead. but for your question.. i'll try to investigate. you did not mention any violent reactions in the flask so i take it as "safe." but for the ozone headache.. i'll take note of it. i'll be careful.
  9. hehehe! nice one! its only the sun that sometimes appears red right?
  10. yes, pollution may be of a factor as to why it behaves like so. but i saw a red colored moon on the horizon when i was in the beach once. i guess i'll still go with the refractive index/ index of refraction. but i'll try searching on possible pollutants dispersed on the air that contributes to this phenomenon.
  11. i did not misunderstand it. in fact, that's how it was said. wew! talk about plagiarism. toinks!!
  12. after reflecting over what i read about blind people. something suddenly popped in my mind. "HOW DO BLIND PEOPLE DREAM." its quite vague since they can't see anything, so how do they go about dreaming? i found an article on the reader's digest which says that they inherit their dreams from their parents who, if not like them, can see. this further lead me to another question: "Dreams come from the subconscious part of the mind right? so the subconsciousness of a person can be inherited? but stilll i'm not satisfied since its just me putting "facts" together. I'd like to hear your opinions and ideas about this.
  13. i guess its because of its angle of elevation. like that of the sun during sunsets and sunrises.
  14. well another thing aside from developing resistance against the medicine is its spectrum of activity. lets take for example cefalexin. this cefalexin when taken is not like a heat-seeking missile that will only 'seek' its locked target. the medicine is like smoke that will engulf anything within the vicinity of infection. so that means even your lymphocytes trying to fight the infection. and if this will be applied to your statement, then your only killing your bacteria or worst -yourself. hehe!
  15. yes, they do. think about the carnivorous plants, venus-flytrap and the pitcher plant from Amazon (err.. was it from the amazon?).
  16. hey... i have a question regarding on earth's magnetic sphere. its been quite bugging me ever since i got it in my physics exam. physicists say that the actual north of the earth is actually the south and that the south is actually the north. i don't quite understand it. i'm sorry for the abrupt question. i'll try to get the given question (from my physics teacher) and i'll try to post it next time. i hope i kinda gave you some idea.
  17. my suggestion, try the sodium metal + water trick. its violent but it will surely stir the whole class. hehe!! sorry its not physics.
  18. its not only methane that powers those cars.. its actually a combination of propane, butane and methane. methane has a low octane rate and it will be impractical to use it for internal combustion that is why it is mixed with some other alkyl groups to increase the octane content. i have a suggestion with regards to the "dump-site- collecting-methane-idea", why not collect some stool (a.k.a. human wastes,not sure on the spelling of "stool", sorry) and condemn it in a container, say a septic tank, and gradually collect the methane produced by the methanogens from the baffles or i think they call it exhaust pipes... if you like, try to search it... my memory is kinda misty. hehe ! xiao!
  19. i guess i'll go with the stress idea of the nosebleeds.. hehe!! i'm so fortunate not to have nosebleeds since i was a baby!! wohhooo!! thx GOD!!
  20. um.. could it be that you are experiencing slight thrombocytopenia? perhaps you have a weak blood vessel in the internal cavities of your nasal passages. and because of thrombocytopenia you experience "nose bleeds" *Thrombocytopenia (or -paenia, or thrombopenia in short) is the presence of relatively few platelets in blood. Signs and symptoms Often, low platelet levels do not lead to clinical problems; rather, they are picked up on a routine full blood count. Occasionally, there may be bruising, nosebleeds and/or bleeding gums. It is vital that a full medical history is elicited, to ensure the low platelet count is not due to a secondary process. It is also important to ensure that the other blood cell types red blood cells, and white blood cells, are not also suppressed.* *http://en.wikipedia.org/wiki/Thrombocytopenia
  21. whoah!! i hate anthropods!! ewww!!!! hehe!! the shark-eating octopus is sooooo awesome!!!! whoooooot!! i'd like to pet one.
  22. err.. i like to call it a gift(ambidexterity) rather than "brain-damaged thing". it seems that they are looking at it pesimistically.. hehe.
